We have multiple DHCP servers that serve at different locations with separate scopes defined on each. We want to move to a centralised 2012 DHCP failover solution.
I've seen lots of articles mentioning migrating from DHCP 2003 to DHCP 2008, using netsh commands to export from 2003 then import the DHCP database to 2008.
Can you use netsh just to export the scopes (IP ranges, reservations, lease info, exclusions etc) from each 2003 DHCP server & import to a centralised 2012 DHCP server. I'm wary of importing one DHCP database from one 2003 server to the 2012 then another db from the next 2003 just for the previous import to be overwritten.
Any advice would be appreciated.
